3 claims.

The present invention relates to a sheet metal container or can adapted to be opened by the removal of a tearing strip and having an annular collar band which is inserted into the can, the invention having particular reference to and having as an object the provision of such a container having' protuberances originally formed in either the can wall or inthe collar band wall which are partially ironed out and are made practically undiscernible by the insertion of the collar into ,the can, but which after such ironing out hold the collar against shifting when it is later utilized as a friction base for the reclosure member produced by removal of the tearing strip.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawing, discloses a preferred embodiment thereof.

Referring to the drawing: j

Figure 1 is a side elevation of a sealed, tearing strip can embodying the instant invention;

Fig. 2 is an enlarged fragmentary vertical section of the upper end of the can shown in Fig. 1,

the view being taken substantially along the line 2-2 in that figure;

Fig. 3 is an enlarged fragmentary horizontalv section taken substantially'along the-line 3-3 in Fig. 1;

Fig. 4 is an enlarged vertical section of fragments of unassembled can parts which when assembled make up the can shown in Fig. l, the view illustrating the parts in superimposed and separated position; and f Fig. 5 is a horizontal section taken substantially along the line 5--5 in Fig. 4 and illustrating one form and location of a protuberance before it is ironed out.

As a preferred embodiment of the invention the drawing discloses a sheet metal can which comprises a tubular member or body I I (Fig. 1) having top and bottom end closures I2, I3 secured thereto by suitable top and bottom seams I4, I5. In the body wall adjacent its upper end there are spaced and parallel score lines I'I, I8 (Figs. 1, 2 and 4) which define a tearing strip I9 adapted to be removed in the usual manner in opening the can and for producing the usual reclosure member or cover.

An annular member or collar band. 2l (Figs. 2

and 4) having upper and lower curled edges 22, is located in the can and frictionally engages the body Wall adjacent the tearing strip and provides a friction base for the reclosure cover when the tearing strip is removed. The lower curled edge (Cl. B20-54) 23 of the collar seats against an inwardly projecting annular bead 25 formed in the body wall below the tearing strip for properly locating the collar. A

It is to the holding of the collar band 2| against turning or vertical displacement relative to the body I I of the can that this invention is particularly directed. When the tea-ring strip is removed and a reclosure cover is formed the collar is used as a base for this reclosure cover and it is ado vantageous that the collar'band be held against turning and against vertical displacement. This holding of the collar band according to the instant invention is effected through the added friction afforded by one or more projections u formed in a wall part of thecompleted can.

These projections may be formed in either the can proper or in its collar and are formed in a wall part before the collar band is inserted. During the insertion .of the collar into the body th'e- 20 projections are partially ironed out and only suiilcient projection remains after the inserting act to sumclently and to frictionally augment the engagement of the collar and the can Wall to hold these parts in exact position relative to each 25 other and to permit the desired use of the collar as a base for the reclosure cover. As a matter of fact these projections may be almost entirely vobliterated while still performing their holding function and there is preferably left only a mere 30 trace of the projection after the collar has been nally seated.

When the can body wall is utilized to contain the holding projections th'e latter take the form of inwardly extending protuberances 21 (Figs. 2 and 3) which are preferably equally spaced from ne another, four being indicated in the drawings, and these are formed in the body Wall intermediate the tearing strip I9 and the bead 25. In this form the stiff lower curled edge 23 of the collar rides against, presses outwardly and reforms the protuberances 21 as the collar band is brought into its seated position 'within the can wall, the frictional engagement of the protuberances 21 with the collar holding the latter against 45 circumferential or vertical displacement relative to the can body wall. The results of this seating and ironing out action are shown in Figs. 2 and 3. When the protuberances are placed in the wall of the collar band they are preferably located just abovevthe lower curled edgey of the collar band as indicated by dot and dash lines at 29 in Fig. ll. lThe curved corner or edge of the'mouth of the can during the insertion of the collar is rst engaged by these .outwardly` extending projections 29 and the projections are ironed out as they are forced down along the can body wall. This action it will be seen is the same as that described for the projection 21 formed in the body wall, as well as the frictional holding function of the projections. l

In either event the same result obtains, namely,

the collar band is firmly seated in position within the can and is prevented from turning or vfrom displacement by the friotional engagement of the ironed out projections, this ironing out feature fairly obliterating any distinct projections so. that they are hardly discernible. Yet, as stated before there is just enough added holding action to accomplishthe desired purpose.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes Amay be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

1. A sheet metal container, comprising a tubular body member having a side wall, a cooperating member having a wall frictionally engageable with said body member side wall and terminating at on'e end in an inwardly curled reeniorcing portion, and a protuberance located in said side wall and .which is engaged by the wall of said cooperating member for frictionally and tightly holding the body and the cooperatingI member in assembled position, said inwardly curled reenforcing portion holding the wall of said cooperating member outwardly against said protuberance to insure against relative displacement between said.

body and cooperating members, said protuberance bengpartially ironed out substantially beyond detection by its engagement with said engaged wall.

. v 2. A sheet metal container, comprising a tubular body having a side wall, an annular collar band insertable in said body and having a wall u engaging said body side wall and terminating at one end in an inward curl, and a protuberance located in said side wall and engaged by the wall of said band for frictionally and tightly holding the body and the collar band in assembled position, said inward curl holding the wall of said band outwardly against said protuberance to insure against relative displacement between said body and band members, said protuberance being partially. ironed out Isubstantially beyond detecf forcing curl holding said collar band outwardly against said protuberance with a tight frictional 30 engagement, whereby relative displacement of said collar band and container body is prevented.-
